Visualizing Swiss politicians on Twitter using D3.js

D3.js (D3: data-driven documents) is a Javascript library for creating complex, static or animated/interactive web graphics using HTML, SVG and CSS. The main site has a short...

Journalists’ Twitter network

So, David Bauer posting a list of 300+ German-speaking, Twitter-using journalists came just right. Scroll down to see the resulting network. By they way, you can find more information on the technical background of...

The map uses a background I made with TileMill and CC-BY-licensed postcode data from the Geonames gazetteer portal. (By the way, here’s an informative short TileMill tutorial by...

ZIPScribble Map: Switzerland – Part II

Having seen a visualization by Robert Kosara of EagerEyes a loooong time ago, I wanted to try to reproduce it for Switzerland using Processing. This is the second installment of a two-parts post covering this project, in which I will describe how to arrive at the final result, the ZIPScribble Map....
